NOTICE! The General Purpose IO are not potential-free and have no protective circuit. Faulty wiring (overvoltage, undervoltage or inverting the wiring when used as serial interface) can result in a damage in the electronics. During operation as serial interface only LVCMOS levels are allowed to the connector pins. To get a serial RS-232 compliant interface, an external level shifter (LVCMOS/RS-232) is required. Applying RS-232 levels directly to the pins as well as mixing up the signals RxD and TxD can destroy the camera electronics! |

Serial interface wiring (UART)
The following figure shows the wiring of the serial interface with GPIO 1 as camera-side output (TxD) and GPIO 2 as camera-side input (RxD). The GPIO must be configured accordingly (see is_IO()).
